How to find strings that are only in one of the two lists?

Analytics

let's say I have
5 lines of code

line1
line2
line3
line4
line5

and there is another code

line6
line5
line2
line1
line4
line3

So you need to remove the lines from the second code that are in the first one and leave only those that are new
line6
. Is there any software / site that can do this?
